To all whom@ magicienne/m:

' Be it `knowny thatl, Soerat) a *citizen ofthe" United,"States,; residing at Spokane, inY Spokane' countyaand Statev of Wasli'in on,have invented certain new and usefulmpiovenients i in liit'onio bile Headlights, of whither@ ione-Wing is, ya, speci@ 'cation. t

. The present-invention relates tonnpi'ove ments in autoniolbile headlights conteniplates' an iinproveddevice for fattaenmentv to eXistiiior lamps?? projected'ftrorn, `the' front thereot vand fdesigri-edny ioartieularly'l orjtlie purpose of directiiigltlie light'frays'from the l'amp'in the properiinreetioii toA achieve the most etiic'ientand eiiie'ctive@distribution of the light, and at f'the'saineItiniejaiording 'a' non-glare headlight 'to' ravoid "sdaznling the: eyes of the operator of an afroreachingvez@ To this end the 'invention consiste'fin the' automobile. head light of a 'casing "or hood projected' combination with a. standard frointhe front o' the headlight lainp eindprovided with 'means for illurninatingv the rcad Way directly in lfront of the movlngvehicle, and Withmeans for insuring the passage oi a beam' of light, for distant. illumination; forwardly, on.y a piene?parallelwitlithe' longitudinal-axis ofthe lei-nip teus obscuriing' from the'eyes of a person 'inf front of the lamp the direet,.d'azzling rays'o lamp, 'atall times,"

except when' the eye. indirectly in" line with the longitudinal axis of the lamp.

By this distribution off the light rays most of the glare from dir rye et the lamp 'is eliminated, provis n ie inade for lat eral distribution of the ye and from the lamp oi front of the l l Mood or distant illumination, as set forth in eoqiending application for Ser. No. 392,362, .l une 28, 1920.

[In the present invention l have improved certain features et the device whereby distant illumination is accomplished and the roadway directly in'i'ront oi1 the automobile may be lighted by properly directed rays.

In the drawings herewith 'forming' a part of this specilicatiorr,-

Figure l is a vertical, longitudinal sectional view of a headlight of standard type having the projector or inaslr ot my invention attached thereto. n l

l In the Y'preferred forni of the invention as' illustrated. in the .drawings a conventional torni. of automobile headlightflamp is Yernployed comprising'the outer -metallic'shell l ofapproved form, and the inner, re-

l tiecting casing 2 for projecting the light rays ably circular in outline, and the front plate" ,ot thev 'lamp is utilized 'for the attachmentl ot the devicpv As lshown in the drawings, the mask'coml; prises a'tubular metallic hood orcasing, ivliich'rat its rear end 1s circular in cross i sectioin/and at its front end as seen in F ig.

2, merges into an elliptical forni in' cross section; the vertical. or shortervdiaineter of the ellipslebeing approximately the sameas the diain'etenof the rear end of the hood,4 and the longitudinal or major dianieterof the ellipse being of siiI'iicient-length vto insure a .lateral distribution of the light rays,

aswelll as directuforWa-rd projection ofthe light raysv from the lamp dof thc/headlight. At the rear`tlie tubular casing' is fashioned withy an outwardly projecting flange 7, rabutting against the ,front plat'ew off the. headlight, and preferably la yhinge .8V ievprolvidediat the top of thehood wherebyv the attachment may be swung away "from the headlight, when 'the fastening- ,screiv freed', to give access to the interiorof the hood Without detaching the device from thev headlight. i

Near the front face of the hool or easing an annular head l0 is provided for strengthening and bracing the saine, and at 11 the front edge of the hood is flanged and curled l over to torin retaining means for the hood lens l2,

Within t-ne nood and extendingI transversely thereof are provided liorizontaiiy L disposed, flat plates With reflecting surfaces Jor directing the light rays received from the reilector 2 of the lamp, and other plates for guiding the light rays directly forward for distant illumination and further for preventing upward distribution of the lightv so f 85,11,

It will also be apparent that the plates 14 will be instrumental in preventing upward distribution of the light rays, thus eliminating undesirable waste of light and concentrating the light beams for forward distribution and distant illumination where needed.

The lower group of tubular members 15, in

the casmg or hood are designed, by their refleeting plates 16 to direct the light rays from the lamp forwardlyand downwardly, directl in front of the automobile, and laterally thereof, the lateral distribution being accomplished by the elliptical formation of the hood at its front end. The members, 15 are fashioned with plates 16, but only the undersurface 16 of each plate is a reflecting surface, the upper surface of each of these plates being blackened to prevent distribution of the light rays in an upward direction. It will be noted that the lower group of reflectinof devices or plates are arranged at an ang e to the vertical plane of the headlight, the degree of angular-ity increasing from the upper to the lower reflecting device for the purpose of directing light rays to the ground directly in front of the automobile. Thus the light rays as shownby dotted lines emanating at the lamp are reflected from Vthe reflector 2 and strike the undersurface or reflecting surface .16 of these reflecting plates with the result that the rays vare directed as shown in dotted lines` to illumine the roadway directly at the front and side of the moving automobile. These reflecting and guide plates are fashioned in tubular form and secured at their ends to the wall of the hood or casing, as by rivets or bolts 17 and exterior nuts 18, the under surface 16 of the plates of the lower group being highly polished reflecting surfaces and the upper surfaces of these plates being nonreflecting surfaces, while the plates of the upper group of members perform the funcfiecting surface of the reflector 2, and the formation ofthe hood, whichis shorter at the bottom than at the top, provides for variation in length of the plates, the longer plates being located at the top of the hood.

What I claim isp The combination with a headlight and lamp, of a hood attached to the lamp, a grou offixed, horizontally arranged and regularly spaced tubular members forming flat plates within the hood for distant distribution of light rays, and a group o f angularly disposed tubular members vforming flat reflecting plates, each of said plates having an under reflecting surface for direct illumination of the 'roadway in the immediate vicinity of the lamp.

In testimony whereof I aflix m si nature.
